Selena Gomez Disses Justin Bieber Again– She Says Her Music Isn't About Him!

Selena gets super-annoyed when a reporter asks about his recent in-concert appearance with her — what gives?

Selena Gomez seems to be crazy about her boyfriend Justin Bieber, but during a recent interview she was not very appreciate of his musical influence!

Selena, 19, was interviewed backstage by E! News about her new tour, and things got super-awkward when Michael Yo asked her about Justin, 17, jumping onstage to sing at her July 24 concert in Costa Mesa, Calif. — she refused answer the question!

“It’s not really about that,” she said abruptly. “I think it’s definitely just about my tour and it’s about all this hard work I’ve done.”

We think Selena should chill out — it’s one thing to keep your relationship a secret, but she certainly didn’t mind Justin stealing the spotlight when he came onstage that night!

What do you think, HollywoodLifers — does Selena not appreciate Justin enough?
